Here is the file from the 09 e90's 5th gear dyno pulls. These were done immediately before the 4th gear pulls. The highlight in blue is an area of slight concern as the power flattens and drops off from somewhere between 7000 rpm and redline. This trend was not observed in any other cars that dyno'd yesterday.

A separate thread with more information will be created as we delve deeper into figuring out what is going on with this car. For comparisons sake, an annotated dyno of Franks car is also posted. You can see that his car pulls much stronger through the upper RPMs and smoothly pulls to redline.

Mine is listed first, then franks to follow. Both runs are SAE corrected.
